Problems solved by technology

However, due to the limited wear resistance of ordinary UV-curable paints, the surface of wooden furniture, wooden floors and other wooden products is prone to scratches or scratches. In order to avoid this situation, consumers usually have to be careful in use, but still Unavoidable scratches
Existing wood surface coatings cannot meet the requirements in this respect, and it is difficult to achieve high-quality products stably in the national standard test
This directly affects the beauty and service life of wooden furniture and wooden floors

Embodiment 1

[0011] A kind of UV-high wear-resistant flow coating topcoat of the present invention is a varnish, wherein the components of the varnish and their weight ratios are: 100% UV resin 60, defoamer 0.5, dispersion Agent 1, Initiator 5, Leveling Agent 1, Wear Resistant Agent 4, Monomer 30. Among the above components: UV resin is trifunctional polyurethane acrylic resin, or difunctional modified epoxy acrylic resin or their mixture, such as those produced by CYTEC, SARTOMER, Changxing, Miki, etc. The anti-wear agent is a modified high-purity, high-hardness inorganic powder, such as Sibelco's minspar10. The monomers are: acrylates, modified acrylates or their mixtures, such as those produced by CYTEC, SARTOMER, Changxing, Miki, etc. The defoaming agent is a silicone-free polymer solution, polyacrylic acid polymer or their mixture, such as BYK055, BYK080A or their mixture produced by BYK. The dispersant is high molecular weight block copolymer solution, modified acrylic block copoly...

Embodiment 2

[0017] Another kind of UV-high wear-resisting flow coating finish paint of the present invention is a matte paint, compared with embodiment 1, only the proportioning of parts by weight is different, the components of the matte paint and the proportioning of parts by weight thereof The ratio is: 100% UV resin 65, defoamer 0.5, dispersant 1, initiator 8, leveling agent 1, matting agent 9, wear agent 3, monomer 20. The matting agent adopts organic modified fumed silica, such as READ2105 produced by American Grace Company or fumed silica, such as matting powder OK500 produced by DEGUSS Company.

Embodiment 3

[0019] Another kind of UV-high wear-resistant flow coating topcoat of the present invention is a varnish. Compared with Example 1, only the proportioning by weight is different. The components and weight ratio of the varnish are: 100% UV resin 70%, defoamer 0.7%, dispersant 0.5%, initiator 4, leveling agent 1, wear agent 2, monomer 25%.

[0020]

[0021] The invention adopts wear-resistant agent and UV resin to improve the wear resistance and surface scratch resistance of the coating topcoat, and the hardness and flexibility are relatively balanced, which improves the noble quality of the wood itself, and the formed paint film structure has good flexibility , Scratch resistant. After use, it can form a beautiful and scratch-resistant protective layer on the surface of wooden furniture, wooden floors and other wooden products, thereby forming a durable protection for the surface of wooden furniture and wooden floors.

Abstract

The invention discloses UV (ultraviolet) high-wear-resistance curtaining finish which comprises, by weight, 60-70 parts of 100% UV resin, 0.4-0.7 part of defoamer, 0.5-1 part of dispersant, 4-8 parts of initiator, 0.5-1 part of leveling agent, 2-4 parts of wear-resisting agent, and 20-30 parts of monomers. The 100% UV resin is hexa-functional polyurethane acrylic resin, tri-functional modified epoxy acrylic resin, or mixture of the hexa-functional polyurethane acrylic resin and the tri-functional modified epoxy acrylic resin. The monomers are acrylates, modified acrylates, or mixture of the acrylates and the modified acrylates. The wear-resisting agent is made of modified high-purity high-hardness inorganic powders. The UV high-wear-resistance curtaining finish is high in wear resistance, high in surface scraping resistance and balanced in flexibility, and can be applied to wooden products such as wooden furniture and wooden flooring to protect the surface of the wooden furniture and wooden flooring for long.

Description

technical field [0001] The invention relates to a UV-light-cured wood coating, in particular to a UV-high wear-resistant curtain coating topcoat with a gloss of 80 to 85 degrees. Background technique [0002] UV is the English abbreviation of Ultraviolet (ultraviolet), and UV paint is ultraviolet light curing paint. Ordinary wood boards, silicon-calcium boards and other boards are painted with UV paint, and then dried by a UV light curing machine to form stone boards. They have bright surface treatment, bright color, strong visual impact, wear resistance, and strong chemical resistance. Long service life, no discoloration, easy to clean, is an ideal plate maintenance treatment process. The surfaces of existing wooden furniture, wooden floors and other wood products all adopt UV paint, that is, UV curing paint maintenance treatment process. However, due to the limited wear resistance of ordinary UV-curable paints, the surface of wooden furniture, wooden floors and other woo...
